Phalaenopsis orchid plant named ‘PHALDUXI’

ABSTRACT

A new and distinct variety of  Phalaenopsis  plant named ‘PHALDUXI’, particularly characterized by white flowers with yellow-white lip with purple stripes, 2 to 3 peduncles, a short and sturdy inflorescence, a narrow obovate leaf shape, and propagated by tissue culture is disclosed.

Genus and species: Phalaenopsis Blume.

Variety denomination: ‘PHALDUXI’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar ofPhalaenopsis plant, botanically known as Phalaenopsis of the Orchidaceaefamily, and hereinafter referred to by the cultivar name ‘PHALDUXI’.

Phalaenopsis comprises a genus of about 60 species of herbaceousperennials many of which, or the hybrids thereof, are suitable forcultivar in the home or greenhouse. Phalaenopsis is predominantlyepiphytic or rock dwelling, and is native to tropical Asia, the MalayArchipelago, and Oceania. The species typically has 2-ranked, fleshy,oblong or elliptic leaves affixed to a short central stem (monopodialgrowth), which vary in size from 12 to 20 cm to over 60 cm. The leavesmay be entirely green or mottled with silver grey.

Phalaenopsis orchids, often referred to as ‘Moth Orchids’ in thehorticultural trade, are frequently used to furnish cut flowers for theflorist trade or sold as flowering potted-plants for home orinteriorscape.

Phalaenopsis produces upright or pendent lateral racemes, often withmany showy flowers which open in succession beginning with thelowermost. The flowers possess three sepals and three petals; thelateral ones being alike. The lowermost petals, called the labellum, isthree-lobed and is often more brightly-colored than the other flowersegments. Flower colors include various shades of pink, white, yellow,and red-brown.

Phalaenopsis orchids are typically propagated from seeds. Asexualpropagation of Phalaenopsis is often done from off-shoots which arisefrom the lower bracts of the inflorescence. The resulting plants aredetached from the mother plants and may be planted in a suitablesubstrate.

The new Phalaenopsis ‘PHALDUXI’ is particularly characterized by itsattractive and unique white flowers, economical propagation by tissueculture, rapid growth, and a plant dimension suitable for packaging andshipping to the market and suitable for both 9 cm and 12 cm pot size.

‘PHALDUXI’ is a product of a planned breeding program conducted inBleiswijk, The Netherlands.

The new Phalaenopsis ‘PHALDUXI’ originated from a cross made in October2005 in Bleiswijk, The Netherlands. The female parent is a whitePhalaenopsis pot plant named ‘23266-02’ (unpatented), while the maleparent is a white Phalaenopsis pot plant named ‘11968-04’ (unpatented).A single plant was selected in January 2009 and has been asexuallyreproduced repeatedly by tissue culture in Bleiswijk, The Netherlandsover a 4-year period. The new variety has been found to retain itsdistinctive characteristics through successive asexual propagations.

Asexual reproduction of ‘PHALDUXI’ by tissue culture was first performedin October 2011 in Bleiswijk, The Netherlands and has demonstrated thatthe new cultivar is firmly fixed and retained through successivegenerations of asexual reproduction.

Plant Breeder's Rights for this variety have been applied for in Europeon Jan. 15, 2013. ‘PHALDUXI’ has not been made publicly available orsold anywhere in the world more than one year prior to the filing dateof this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishingcharacteristics of this new cultivar when grown under normalhorticultural practices in Bleiswijk, The Netherlands.

-   -   1) White flower with yellow-white lip with purple stripes;    -   2) 2 to 3 peduncles;    -   3) Inflorescence is short and sturdy;    -   4) The shape of the leaf is narrow obovate; and    -   5) Plants are propagated by tissue culture.

DESCRIPTION OF THE PHOTOGRAPHS

This new Phalaenopsis plant is illustrated by the accompanyingphotographs which show the overall plant habit including blooms, budsand foliage of the plant; the colors shown are as true as can bereasonably obtained by conventional photographic procedures. Thephotographs are of a 40-week old plant grown in a greenhouse inBleiswijk, The Netherlands in May 2013.

FIG. 2 shows a close-up of the flower of ‘PHALDUXI’.

FIG. 3 shows a close-up of the leaves of ‘PHALDUXI’.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctivecharacteristics of ‘PHALDUXI’. The data which define thesecharacteristics were collected from asexual reproductions carried out inBleiswijk, The Netherlands. The plant history was taken on 40-week oldplants which were planted from tissue culture in 9 centimeter pots andgrown in a greenhouse between 27° C. to 29° C. for 20 weeks, continuedby a cooling period of 8 weeks between 18° C. to 20° C. and 12 weeks ina greenhouse of 21° C. Observations were made in May 2013. Colorreadings were taken under 5000 lux natural light in the greenhouse.Color references are primarily to The R.H.S. Colour Chart of The RoyalHorticultural Society of London (R.H.S.) (2001).
